These dimensions include the easiness and broad spectrum of participation, the provision of value in return to the contributions, the visibility of community activity, the support of different levels of membership, the openness to the external world, and the support for evolving phases of the community life. In this paper we present a system that has been designed in order to tackle those dimensions with a particular attention to participation issues. We present first the sources of requirements that have informed the system design and which include the user observation of two companies. Then we present the system, stressing the features of integration with the daily working environment and the provision of multiple situated views, as a means to address the elicited requirements. Finally, we compare our design choices with a broader set of requirements that we have derived from literature.enText10.1007/1-4020-3591-8_23
